9 Claims.

Wringers are usually provided with a water board or clothes guide and it is desirable to have such boards detachable in order to facilitate the shipping of wringers and also for servicing 5 wringers. The present invention. is designed to simplify the method of attachment of clothes guides or water boards. Features and details of the invention will appear from the specification and claims.

A preferred embodiment of the invention is illustrated on the accompanyingdrawing as follows:

Fig. 1 shows a front elevation of the wringer,- a part being broken away to better shown con- 15 struction.

Fig. 8 is a section on the line t-8 in Fig. 3.

l marks the base of the wringer frame, 2-2 the stiles of the frame, 3-3 the wringer rolls for the shafts, 4 the shafts of the rolls, 5 the bearings for the rolls which are mounted in the side 39 stiles, ii a wringer top which ordinarily is detachable, as shown having a release device to which is adapted to release the top by release mechanism not shown.

The base i is trough-shaped, having a slight M flange at the upper edge of the trough. The wringer-is provided with the usual roll guards i which, as shown, are formed in a separate piece from the stile, but in any event these forma part of the side frames. They are provided with the w inwardly extending flanges la which overlap slightly the ends of the rolls. The flange ordinarily extends around the bottom of the guard, delivering water to the inside of the wringer and terminates at the upper edge of the guard as $5 shown in Fig. 4. These parts are, or may be, of

common construction. I r

A water board 9 is formed of sheet metal, is provided with a skirt Hi around the lower edge and has a down-turned flange I! along the roll 50 side of the water board. The waterboard is providcd with end walls. These end walls are formed by a fold in the sheet metal. forming a face l2,

wall at the inner edge of the inner face l3 has an out-turned flange l5 and the flanges at the opposite walls are adapted to be inserted into flanges or vertical lips in the frame carried by the guards theguards in effect being a part of the stiles. 5 The water board as it is forced down in the guards brings the flange H into contact with the edge of the trough i. It will be noted that the engaging lips are oppositely placed, those on the frame being opposite to each other extending oppositely, m and those on the side of the water board extend ing oppositely to each other and to the engaging lips on the frame. The flange l5 extends from its face of the wall toward the opposite wall so that when the water board is in place, the interlocking in means afforded by these flanges are behind and covered by the end wall, thus leaving the exterior, or parts in sight, unobstructed and smooth so that the finish, such as enamel or other finish of a metal, may not be marred by the assembly or unsightly parts left in view. It willalso be noted that the assembly may be made by telesc'opic movement of the flanges or lips relatively to each other. As indicated in the present instance the water board is assembled by a down- 25 ward movement of the flanges or lips from the top thereof to their final location. In this way the water board may be quickly assembled and very securely attached to the frame without extra parts or extra labor. The inner engagement of the lips or flanges of the sides and the frame, extended as they are, permit of these being struck up or formed in directly from the metal of the sides and frame, and the extent of the engagement makes the mounting of the water board very secure.

Ordinarily there is a water board at both the front and rear of the wringer, and preferably the two water boards are secured together. This is accomplished in the present invention by bridge w plate it which is secured by fastening means H on the insides of the skirts Ill at the ends of the board. The bridge piece extends around the lower end of the frame and forms a down hold for the water board. With the top bar removed the assembled water board may be passed down over the side stiles and the flanges, and the two sides will enter the flanges at the front and rear of the guards, and thus definitely secure the water board rigidly in place on the wringer face. Preferably w also the guards are slotted at lb, this slot extend= ing slightly into the face of the guard. A- projection 15a is formed on the edge of the flange which extends into the slot and forms a down hold. The projection is beveled on its under edge 1. In a wringer, the combination of a frame comprising a base and side stiles, the frame having vertically extending lips along the stiles; a water board having sides with opposing vertically extending lips, each lip projecting sidewise from the board side and opposing and interlocking with a lip on the frame; and resilient fastenin means arranged between the flanges for locking the water board in its assembled position.

2. In a wringer, the combination of a frame comprising a base, side stiles and roll guards, said guards having flanges extending vertically and inwardly longitudinally of the frame; wringer rolls mounted in the stiles; and a water board of sheet metal having side walls'thereon formed of a fold of metal comprising outer and inner faces, the inner walls of the folds having outwardly turned flanges extending behind the guard flanges.

3. In a wringer, the combination of a frame comprising a base, side stiles and roll guards, said. guards having flanges extending vertically and inwardly longitudinally of the frame; wringer rolls mounted in the stiles; and a water board of sheet metal having side walls thereon formed of a fold of metal comprising outer and inner faces, the inner faces of the walls having outwardly turned flanges extending behind the guard flanges, said flanges being adapted to be assembled by sliding the flanges along each other into interlocking position.

4. In a wringer, the combination of a frame comprising a base, side stiles and roll guards, said guards having flanges extending vertically and inwardly longitudinally of the frame; wringer rolls mounted in the stiles; and water boards at the front and rear of the wringer, said boards being joined at their ends by a bridge piece, each of said boards being formed of a fold of metal comprising outer and inner faces, the inner wall of the fold having outwardly turned flanges extending behind the guard flanges, the stiles, guards and bridge piece being related to permit the assembly of the board into place with relation to the guards from the top of the wringer,

5. In a-wringer, the combination of a frame comprising a base, side stiles and roll guards,

said guards having flanges extending vertically and inwardly longitudinally of the frame; wringer rolls mounted in the stiles; and a water board of sheet metal having side walls thereon formed of a fold of metal comprising outer and inner faces, the inner walls of the folds having outwardly turned flanges extending behind the guard flanges and engageable by sliding relative movement; and a down hold means on the side walls of the water board engaging the frame, said means going into engagement as the flanges are slid into place.

6. In a wringer, the combination of a frame comprising a base, side stiles and roll guards, said guards having flanges extending vertically and inwardly longitudinally of the frame; wringer rolls mounted in the stiles; and a water board of sheet metal having side walls thereon formed of a fold of metal comprising outer and inner faces, the inner walls of the folds having outwardly turned flanges extending behind the guard flanges, said flanges having interlocking members engageable with the water board as the water board is moved downwardly locking the water board against a return movement.

7. In a wringer, the combination of a frame comprising a base and side stiles, the frame having vertically extending lips along the stiles; and a water board having side walls each formed of a fold of metal comprising outer and inner faces, oneof said faces having a flange extending toward the opposite face of the wall and engaging the lip on the frame, said flange and lip being behind the wall when the board is in position on the frame.

8. In a wringer, the combination of a frame comprising outer and inner faces; and interlocking means between the edge of one face of each wall and the frame, said means being behind the wall when the water board is in place.

9. In a wringer, the combination of a frame comprising a base and side stiles; a water board having side walls each formed of a fold of metal comprising outer and inner faces; and interlocking means between the edge of one face of each wall and the frame, said means. being slidabiy connectable through a manipulation of the board and positioned behind the wall when the water board is in place.
